We present a piezoelectric-driven uniaxial pressure cell that is optimized for muon spin relaxation and neutron scattering experiments and that is operable over a wide temperature range including cryogenic temperatures. To accommodate the large samples required for these measurement techniques, the cell is designed to generate forces up to ∼1000 N. To minimize the background signal, the space around the sample is kept as open as possible. We demonstrate here that by mounting plate-like samples with epoxy, a uniaxial stress exceeding 1 GPa can be achieved in an active volume of at least 5 mm3. We show that for practical operation, it is important to monitor both the force and displacement applied to the sample. In addition, because time is critical during facility experiments, samples are mounted in detachable holders that can be rapidly exchanged. The piezoelectric actuators are likewise contained in an exchangeable cartridge.

用于μ子自旋弛豫和中子散射实验的压电驱动单轴压力盒

我们提出了一种压电驱动的单轴压力传感器，它针对 μ 子自旋弛豫和中子散射实验进行了优化，并且可以在很宽的温度范围内运行，包括低温。为了适应这些测量技术所需的大样本，该单元被设计为产生高达 1000 N 的力。为了最小化背景信号，样本周围的空间尽可能保持开放。我们在这里证明，通过使用环氧树脂安装板状样品，可以在至少 5 mm3 的有效体积中实现超过 1 GPa 的单轴应力。我们表明，对于实际操作，监测施加到样品上的力和位移是很重要的。此外，由于在设施实验期间时间至关重要，因此样品安装在可快速更换的可拆卸支架上。
